“As a rapporteur on renewable energy, I witnessed how thin the factual basis is for predictions that are made at the IPCC.”

Vahrenholt said views laid out in his book The Cold Sun will “will make me enemies in all camps”.

He claims new studies have “seriously questioned” the impact of carbon dioxide on global warming.

“CO2 alone will never cause a warming of more than 2 degrees Celsius by the end of the century,” he added.

“I say that global warming will remain below two degrees by the end of the century.

“My concern is that if citizens discover that the people who warn of a climate disaster are only telling half the truth, they will no longer be prepared to pay higher electricity costs for wind and solar.

“I am indeed saying that climate change is manageable, because the cooling effects of the sun and the ocean currents give us enough time to prepare.”
